Elastance (S) is the reciprocal of capacitance (C).

The formula for capacitance (C) is charge (Q)/voltage (V) and formula for elastance (S) is voltage (V)/charge (Q) .

The unit of capacitance is Farad and unit of elastance is Daraf.

The reciprocal of capacitance is Elastance.

The reciprocal of capacitance is called elastance, and its unit is the reciprocal farad, also called the daraf.
